Conservative MP Damian Collins MP asks the BBC Director-General if he accepts if it was not for ITV there would be no investigation.
George Entwistle said: "Yes I accept that it is a matter of great regret."
Amid the fallout from the Jimmy Savile scandal the BBC is investigating nine allegations of sexual harassment among staff and contributors.
BBC boss George Entwistle has spent almost two hours taking questions from MPs about the corporation's handling of the Savile scandal.
Ex-BBC boss Mark Thompson has told ITV News he will help with any inquiry into the corporation and its handling of the Savile allegations.
